Run-length encoding (RLE) is a form of lossless data compression in which runs of data (consecutive occurrences of the same data value) are stored as a single occurrence of that data value and a count of its consecutive occurrences, rather than as the original run. For example, a sequence of "green green green green green" in an image built up from colored dots could be shortened to "green x 5".
